Answer:

A. The graph is a line that goes through the points (9,0) and (0,6).

Step-by-step explanation:

Given

4x + 6y = 36

Required

Select the true options

(a)\ (9,0)\ and\ (0,6)

This implies that"

(x_1,y_1)= (9,0)

(x_2,y_2)= (0,6)

So, we have: (x_1,y_1)= (9,0)

4x + 6y = 36

4 * 9 + 6 * 0 = 36 + 0 = 36

So, we have: (x_2,y_2)= (0,6)

4 * 0 + 6 * 6 = 0 + 36 = 36

<em>Hence (a) is true.</em>

Given: AB ∥ DC
RSB [31]

Answer:

A=1,720.16\ units^2

Step-by-step explanation:

we know that

The area of the trapezoid is equal to

A=\frac{1}{2}(DC+AB)DE

step 1

Find the measure of angle DAE

m∠ADC+m∠DAE=180° -----> by consecutive interior angles

we have

m∠ADC = 134°

substitute

134°+m∠DAE=180°

m∠DAE=180°-134°=46°

step 2

In the right triangle ADE

Find the length side AE

cos(∠DAE)=AE/AD

AE=cos(46\°)(40)\\AE=27.79\ units

step 3

In the right triangle ADE

Find the length side DE

sin(∠DAE)=DE/AD

DE=sin(46\°)(40)\\DE=28.77\ units

step 4

Find the area of ABCD

A=\frac{1}{2}(DC+AB)DE

we have

DC=32\ units\\AB=DC+2(AE)=32+2(27.79)=87.58\ units\\DE=28.77\ units

substitute

A=\frac{1}{2}(32+87.58)28.77

A=1,720.16\ units^2

sergejj [24]

Answer: option c.

Step-by-step explanation:

To solve the exercise you must apply the formula given in the problem, which is the following:

y=33,430e^{0.0397t}

The problem asks for the projected population of Bakersfield in 2010.

Therefore, keeping on mind that  <em>t </em>is th number of years since 1950, you have that:

t=2010-1950\\t=60

Substitute the value of <em>t </em>into the formula.

Therefore, you obtain:

 y=33,430e^{0.0397(60)}=361,931
